Problems solved by technology

[0002] At present, the shape and appearance of the absorbent body of sanitary napkins sold on the market are straight or fan-tailed. There are many product types and sizes and specifications. They are in the form of single demoulding and forming boxes. Pressure adsorption weakens the air volume covered by the wood pulp fiber after molding, resulting in the inability to completely evenly distribute the polymers, and the polymers on both sides of the longitudinal direction are too large. Due to the equipment process, the polymers on both sides are adsorbed and transferred to leaks, resulting in waste of materials and failure to achieve the absorption effect. At the same time, when the human body uses the product, it will form an outer bow according to age, fat and thin, use posture and habits. When the human body excretes, the product absorbs excessively in an instant and causes overflow, which affects the use effect

Embodiment Construction

[0019] In this embodiment, the absorbent article is a sanitary napkin. Of course, the present invention is not limited to sanitary napkins, it can also be used in other products such as baby diapers and diapers. In this embodiment, such as figure 1 As shown, the sanitary napkin is elongated. Such as figure 2 As shown in the schematic cross-sectional exploded view of the sanitary napkin, the sanitary napkin has a liquid-impermeable leak-proof layer 1 and a liquid-retaining absorbent layer disposed above the leak-proof layer 1. The absorbent layer includes an absorbent body 2 that can hold liquid And a liquid-permeable surface layer 3 arranged above the absorbent body 2, a groove 4 is arranged in the middle of the absorbent body 2, the thickness of the entire absorbent body 2 is 5-7mm, and the thickness of the groove 4 is The width of the side wall formed by the groove 4 of the absorber 2 is 5-10 mm. The groove 4 can lock the excrement in time, and the side wall formed in the ...

Abstract

The invention provides an absorptive article which is longitudinally long in shape. The absorptive article comprises an anti-leak layer preventing liquid permeation and an absorption layer which is arranged over the anti-leak layer and can retain liquid. The absorption layer comprises an absorption body capable of retaining liquid and a surface layer which is arranged over the absorption body and allows liquid permeation. The middle portion of the absorption body is provided with a groove. The absorptive article can rapidly absorb excretion matter and prevent reverse permeation, thereby solving the problem of side leak.

Description

Technical field [0001] The present invention relates to the field of sanitary care products, in particular to absorbent articles, which are suitable for feminine sanitary products, baby diapers, and adult care products. Background technique [0002] At present, the shape and appearance of the absorbent body of the sanitary napkins sold on the market are straight or fan-tailed. The product types and specifications are many. Single strip demoulding and forming boxes are used. Wooden paddles are mixed with polymers. The pressure absorption reduces the air volume covered by the wood pulp fiber after molding, resulting in the incompletely uniform distribution of the polymer, and the large polymer on both sides of the longitudinal direction. Due to the equipment process, the polymer on both sides is absorbed and transferred, resulting in material waste and failure to achieve the absorption effect At the same time, when the human body uses the product, according to age, weight, posture ...
